Iron is an important mineral to plant humans and animals. It helps the blood cells to give oxygen to the rest of your body. Vitamin C helps you to take in iron. Low levels of iron in the human body result to anemia. Anemia is when a person's blood has a lower than normal number of red blood cells. To avoid anemia you'll have to have a rich diet of fruits such as apples, bananas, apricots and plums; vegetables such as asparagus, squash, yams, broccoli and leafy greens; red meat; tofu; and whole grains.
